MULE OR PUSHER CAR.

SPECIFICATION forming part of Letters Patent N 0. 774,166, dated November 8, 1904.

Application filed August 6 1904- To all whom it may concern:

Be it known that I, E310 ESSELIUS, a resident of Steubenville, in the county of Jefi'erson and State of Ohio, have invented certain new and useful Improvements in Mule or Pusher Cars; and 1 do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved mule or pusher car, the object of the invention being to provide an improved construction of car adapted to push a car or train of cars up a grade or incline and move beneath .the main track. permitting the cars to be moved over the same in position to be engaged by the pusher-car behind; and the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in longitudinal section of a track and pit for my improved car. Fig. 2 is a plan view thereof. Fig. 3 is a view in side eleva-' tion of my improved car. Fig. iis a bottom plan View thereof, and Figs. 5 and 6 are views of opposite ends of the car.

1 represents the rails of the main track, and 2 the rails of the track on which run my improved mule or pusher car 5, said track 2 being of narrow gage and located inside track 1, and at the bottom of the grade or incline drop down below track 1 into a pit 3, having bow-springs 4 at opposite sides to engage enlargements 3* on the sides of mule or pusher car 5 and stop and hold the car by friction of the springs thereagainst.

The car 5 has a frame 6, comprising one integral casting having recesses to receive coiled springs 7, resting on journal-boxes 8, in which are mounted the journals of wheels 9, mounted to run on rails 2.

10 represents my improved push-bar, which is disposed at an incline on the car-frame 6, and its rear end, which is bifurcated to accommodate the pull-bar 11, is pivotally secured upon a cross rod or bolt 12, secured in Serial No. 219,742. (No model.)

depending arms 13 near the rear of frame 6. 5 The pull-bar 11, to which the haulage-cable is secured, extends through a bracket 14, pivotally secured on rod or bolt 12, and its end is screw-threaded to receive nuts 15 and a washer 16, between which and the bracket 1 a coiled spring 16 is located on the pull-bar to give elastic connection of the pull-bar with the car.

The push-bar 1O normally rests on an inclined cross-web 17 of car-frame 6 and is elas- 6o tically supported thereon by a coiled spring or springs 18, which latter are located in pockets 19 in the frame-top and on rods 20, connected by links 21 with bar 10 and provided on their upper ends with nuts 22 and washers 23, bear- 5 ing against the springs and by means of which theltension of the springs can be adjusted at Wil y In operation the mule or pusher car 5 is in pit 3, andthe car to be shoved up the incline 7 is moved across the pit to a point in advance of the entrance thereto. The haulage-cable is then operated to draw the car 5 up out of the pit and compel its pusher-bar 10, which is shaped to fit any ordinary form of coupler, to engage the coupler of the car, and a continued movement of the mule or pusher car will push the other car up the incline, and

when it reaches the top the mule or pusher car is allowed to descend by gravity or other- 30 wise into pit 3 ready for the next car.

By pivotally securing my improved pusherbar at the rear end under the car-frame and elastically holding it by springs and attaching the haulage-cable to the pivot of the pusher- 5 bar the car is permitted to run on the vertically-curved track without any tendency of lifting the mule-car wheels off the track when the pusher-bar is engaged with the coupling of the car to be moved, as the bar 10 can work 9 up and down and the frame of "the car move on its supporting-springs to accommodate the parts to the shifting positions they must assume.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the p recise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A mule or pusher car, comprising aframe mounted on Wheels, of a pusher-bar projecting in advance of the car and pivoted at its rear end below the frame near the rear end of the latter, and elastically held in position.

2. Amule or pusher car, comprisingaframe mounted on wheels, of a pusher-bar projecting in advance of the car and pivoted at its rear end below the frame near the rear end of the latter, and a pull-bar connected with the pivotal point of the pusher-bar.

3. A mule or pusher car comprising aframe elastically supported on wheels, an inclined pusher-bar projecting in advance of the car and pivoted at its rear end below the frame near the rear end of the latter, and a pull-bar connected with the pivotal point of the pusherbar.

4:. A mule'or pusher car, comprising a frame consisting of one integral casting mounted on wheels, an inclined pusher-bar projecting in advance of the frame and pivoted at its rear end thereto, and a pull-bar connected with said frame.

5. A mule or pusher car, comprising a frame mounted on wheels, a pivoted pusher-bar connected therewith, and a spring elastically supporting or holding said pusher-bar.

6. A mule or pusher car, comprising a frame, springs supporting the frame on wheels, an inclined pivoted pusher-bar on the frame, and springs elastically holding said bar.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

ERIC ESSELIUS.
